Dynamic regulation of beta(2) integrin-dependent adhesion is critical for a wide array of T cell functions. We previously showed that binding of high-affinity alpha(4)beta(1) integrins to VCAM-1 strengthens alpha(L)beta(2) integrin-mediated adhesion to ICAM-1. In this study, we compared beta(2) integrin-mediated adhesion of T cells to ICAM-1 under two different functional contexts: alpha(4) integrin signaling during emigration from blood into tissues and CD3 signaling during adhesion to APCs… CONTINUE READING
